The group arrived at the Jomo Kenyatta International Airport, Nairobi and were processed by immigration officials with the Somalis being deported to their country.
It is not clear why they were deported.
It came ahead of President Donald Trump’s expected signing of executive orders starting on Wednesday that include a temporary ban on most refugees and a suspension of visas for citizens of Syria and six other Middle Eastern and African countries.
Trump, who tweeted that a "big day" was planned on national security on Wednesday, is expected to ban for several months the entry of refugees into the United States, except for religious minorities escaping persecution, until more aggressive vetting is in place.
Another order will block visas being issued to anyone from Syria, Iraq, Iran, Libya, Somalia, Sudan and Yemen, said the aides and experts, who asked not to be identified.
